Thanks Alpha, please count me in. I'm currently using free version.

Following are my use for Sandboxie:
1. Running IE browser. I have IE6.
2. Running trial and sharewares. The purpose is to keep them using after the trial period, as there would be no traces left.
3. Running GAOTD offerings to get the installer
4. Try, test and review the softwares.
5. All the portable softwares that I download, I always run them in Sandboxie. These includes the portables for the PRO/paid versions also.
6. Any new software which I have never used before, I execute in Sandboxie.
